I work in a machine shop full of racers who love to build billet parts with our 10 CNC machines on weekends. Billet heads, billet intake manifolds, billet billets, etc.....
If we could work out a specification for a H/W adapter plate, I could probably build billet ones of stainless or aluminum with smiles and cooperation of all sorts...then I could have one, too.
The EGR adapter on the late '70s Fairmont engines took the place of the hot water plate on the earlier engines. If I modeled an adapter to this height, would it be the same as the height of the hot-water adapter? I've never seen one of these hot-water things with my own eyes, just pictures.
The later heads also had a 1.75" opening, where the old 'stangs and Falcons usually had 1.5" openings. I don't think I can get away with 2 designs, just one - so I'd go with the larger one. I have Autocad and we use MasterCam and Solidworks for the CNC modeling, so we're ready for the big time, just need to figure out what could work and I need to find a H/W carb that's jetted for these 200 engines.
Where can I find a reasonably-priced H/W that's already set up?
